Certain Terminology

As used herein and in the appended claims, the singular forms “a,” “and,” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to “an agent” includes a plurality of such agents, and reference to “the composition” includes reference to one or more compositions (or to a plurality of compositions) and equivalents thereof known to those skilled in the art, and so forth. When ranges are used herein for physical properties, such as molecular weight, or chemical properties, such as chemical formulae, all combinations and sub-combinations of ranges and specific embodiments therein are intended to be included. The term “about” when referring to a number or a numerical range means that the number or numerical range referred to is an approximation within experimental variability (or within statistical experimental error), and thus in some embodiments, the number or numerical range varies between 1% and 10% of the stated number or numerical range. The term “comprising” (and related terms such as “comprise” or “comprises” or “having” or “including”) is not intended to exclude that in other certain embodiments, for example, an embodiment of any composition of matter, composition, method, or process, or the like, described herein, may “consist of” or “consist essentially of” the described features.

Definitions

As used in the specification and appended claims, unless specified to the contrary, the following terms have the meaning indicated below.

“Pharmaceutically acceptable salt” as used herein includes both acid and base addition salts. In some embodiments, the pharmaceutically acceptable salt of any one of the compounds described herein is the form approved for use by the US Food and Drug Administration. Preferred pharmaceutically acceptable salts of the compounds described herein are pharmaceutically acceptable acid addition salts and pharmaceutically acceptable base addition salts.

“Pharmaceutically acceptable acid addition salt” refers to those salts which retain the biological effectiveness and properties of the free bases, which are not biologically or otherwise undesirable, and which are formed with inorganic acids such as hydrochloric acid, hydrobromic acid, sulfuric acid, nitric acid, phosphoric acid, hydroiodic acid, hydrofluoric acid, phosphorous acid, and the like. Also included are salts that are formed with organic acids such as aliphatic mono- and dicarboxylic acids, phenyl-substituted alkanoic acids, hydroxy alkanoic acids, alkanedioic acids, aromatic acids, aliphatic and aromatic sulfonic acids, etc. and include, for example, acetic acid, trifluoroacetic acid, propionic acid, glycolic acid, pyruvic acid, oxalic acid, maleic acid, malonic acid, succinic acid, fumaric acid, tartaric acid, citric acid, benzoic acid, cinnamic acid, mandelic acid, methanesulfonic acid, ethanesulfonic acid, p-toluenesulfonic acid, salicylic acid, and the like. Exemplary salts thus include sulfates, pyrosulfates, bisulfates, sulfites, bisulfites, nitrates, phosphates, monohydrogenphosphates, dihydrogenphosphates, metaphosphates, pyrophosphates, chlorides, bromides, iodides, acetates, trifluoroacetates, propionates, caprylates, isobutyrates, oxalates, malonates, succinate suberates, sebacates, fumarates, maleates, mandelates, benzoates, chlorobenzoates, methylbenzoates, dinitrobenzoates, phthalates, benzenesulfonates, toluenesulfonates, phenylacetates, citrates, lactates, malates, tartrates, methanesulfonates, and the like.

M. et al., “Pharmaceutical Salts,” Journal of Pharmaceutical Science, 66:1-19 (1997), which is hereby incorporated by reference in its entirety). Acid addition salts of basic compounds may be prepared by contacting the free base forms with a sufficient amount of the desired acid to produce the salt according to methods and techniques with which a skilled artisan is familiar.

“Pharmaceutically acceptable base addition salt” refers to those salts that retain the biological effectiveness and properties of the free acids, which are not biologically or otherwise undesirable. These salts are prepared from addition of an inorganic base or an organic base to the free acid. Pharmaceutically acceptable base addition salts may be formed with metals or amines, such as alkali and alkaline earth metals or organic amines. Salts derived from inorganic bases include, but are not limited to, sodium, potassium, lithium, ammonium, calcium, magnesium, iron, zinc, copper, manganese, aluminum salts and the like. Salts derived from organic bases include, but are not limited to, salts of primary, secondary, and tertiary amines, substituted amines including naturally occurring substituted amines, cyclic amines and basic ion exchange resins, for example, isopropylamine, trimethylamine, diethylamine, triethylamine, tripropylamine, ethanolamine, diethanolamine, 2-dimethylaminoethanol, 2-diethylaminoethanol, dicyclohexylamine, lysine, arginine, histidine, caffeine, procaine, N,N-dibenzylethylenediamine, chloroprocaine, hydrabamine, choline, betaine, ethylenediamine, ethylenedianiline, N-methylglucamine, glucosamine, methylglucamine, theobromine, purines, piperazine, piperidine, N-ethylpiperidine, polyamine resins and the like. See Berge et al., supra.

As used herein, “hydrates” are compounds that contain either stoichiometric or non-stoichiometric amounts of water, and, in some embodiments, are formed during the process of crystallization with water. Hydrates are meant to include the hydrates of any one of the compounds described herein that is approved for use by the US Food and Drug Administration.

The term “acceptable” with respect to a formulation, composition or ingredient, as used herein, means having no persistent detrimental effect on the general health of the subject being treated.

The terms “administer,” “administering,” “administration,” and the like, as used herein, refer to the methods that may be used to enable delivery of compounds or compositions to the desired site of biological action. These methods include, but are not limited to, oral routes, intraduodenal routes, parenteral injection (including intravenous, subcutaneous, intraperitoneal, intramuscular, intravascular or infusion), topical, and rectal administration. Those of skill in the art are familiar with administration techniques that can be employed with the compounds and methods described herein. In some embodiments, the compounds and compositions described herein are administered orally.

The term “subject” or “patient” encompasses mammals. Examples of mammals include, but are not limited to, any member of the Mammalian class: humans, non-human primates such as chimpanzees, and other apes and monkey species; farm animals such as cattle, horses, sheep, goats, swine; domestic animals such as rabbits, dogs, and cats; laboratory animals including rodents, such as rats, mice and guinea pigs, and the like. In one aspect, the mammal is a human.

As used herein, “treatment” or “treating” or “palliating” or “ameliorating” are used interchangeably herein. These terms refer to an approach for obtaining beneficial or desired results including but not limited to anti-diabetic effect, therapeutic benefit and/or a prophylactic benefit. By “therapeutic benefit” or “anti-diabetic effect” is meant eradication or amelioration of the underlying disorder being treated. A therapeutic benefit is achieved with the eradication or amelioration of one or more of the physiological symptoms associated with the underlying disorder (e.g., an improvement in: hyperglycemia, polyuria, polydipsia, polyphagia, diabetic dermadromes, etc.) such that an improvement is observed in the patient, notwithstanding that the patient may still be afflicted with the underlying disorder. Also, a therapeutic benefit is achieved with the eradication or amelioration of one or more of the complications associated with the underlying disorder (e.g., cardiovascular disease). For prophylactic benefit, the compositions may be administered to a patient at risk of developing a particular disease, or to a patient reporting one or more of the physiological symptoms of a disease, even though a diagnosis of this disease may not have been made.

The terms “diabetes” and “diabetes mellitus” are used interchangeably herein. These terms refers to type 1 diabetes mellitus, type 2 diabetes mellitus, complications of diabetes mellitus, and of neighboring disease states.

EXAMPLES

The examples set forth below are provided to give those of ordinary skill in the art with a complete disclosure and description of how to make and use the claimed embodiments, and are not intended to limit the scope of what is disclosed herein. Modifications that are obvious to persons of skill in the art are intended to be within the scope of the following claims.

Example 1: Study of the effects of a combination of a DPP IV inhibitor, a biguanide, and an SGLT2 inhibitor on Whole Blood Glucose (WBG), Glycated Haemoglobin (HbA1c), Insulin, and Creatinine levels.

Study design:

-   -   Zucker rat model of diet induced diabetes (Zucker Diabetic Fatty         Rats)     -   Parallel randomized study     -   10 animals in each of 4 treatment groups     -   21 days of treatment

Main study outcomes:

-   -   Glucose (measured at multiple time points before and during         treatment)     -   HbA1c (before and at the end of the treatment period)     -   Insulin (before and at the end of the treatment period)     -   Creatinine (before and at the end of the treatment period)

Ten Zucker Diabetic Fatty (ZDF) rats were randomly allocated to each of the four different treatment groups (Table 6). Whole blood glucose measurements were made from 4 days before dosing, then daily until for 8 days, then at reduced frequency. Measurements of HbA1c and creatinine were made the day prior to dosing, then at days 9 and 21. Insulin measurements were made the day prior to dosing then on day 20. A clinical chemistry sample from one animal in the vehicle group on day 9 was not available so there is a missing measurement for creatinine and HbA1c on that day

Methods Statistical Analysis

Whole blood glucose, HbA1c and Creatinine were each analyzed using a linear mixed mode (proc mixed in SAS/STAT 14.2). For WBC, unstructured, autoregressive, exchangeable and Toeplitz correlation structures for repeated measurements across the study were compared using Akaike Information Criterion and Bayesian Information Criterion. The Toeplitz correlation structure was selected as the best fitting structure. For HbA1c and Creatinine an exchangeable structure was used as there were only two measurements. Denominator degrees of freedom were calculated using the between-within subject method. The model included coefficients for baseline measurement (the closest measurement preceding dosing), type of drug treatment, time and an interaction between drug treatment and time. Marginal means (with 95% confidence intervals) for the measurement at each period for each drug were estimated, and an overall marginal mean (with 95% confidence interval) for measurements across time was estimated using weights that reflect the differing amounts of time in each measurement period (assuming each measurement represented all time since the preceding measurement). A likelihood ratio test of overall differences between treatment was initially used, if significant (p<0.05) then we tested for differences between each combination of treatments.

For Insulin, a baseline measure and a measurement at day 20 was available, so the ANCOVA approach (linear regression with the baseline value as a covariate) was used to test for differences in this measurement between treatments. The interaction between baseline value and treatment was tested but there was no evidence of an interaction, therefore the main effects were retained.

To test for robustness of the linear mixed model and ANCOVA models a bootstrapped 95% CI (percentile method) for the weighted marginal mean of measurements across the entire study period or single outcome measurement using 2000 replicates was estimated. The bootstrap sampling was done on individual animal (using complete measurements), with stratification by treatment type.

Results

It was found that there is an overall difference among treatments for the primary outcome WBG (p<0.001, Table 7), and the secondary outcomes of HbA1c (p<0.0001, Table 8), Insulin (p<0.0001, Table 9), and Serum Creatinine (p<0.0001, Table 10).

For WBG, Composition A (p<0.0001) and Composition B (p=0.0026) groups were significantly lower across the post-dose measurement period. Composition A lowered WBG by 205 mg/dL relative to the vehicle, and Composition B lowered WBG by 47 mg/dL relative to the vehicle. There was significant interaction between time and treatment (p<0.0001), with WBG increasing by small amount in most of the treatments except for Composition B (FIG. 1). GMR-4b had a similar WBG to other treatments immediately after dosing (day 1), but then declined and stayed lower for the remainder of the study period.

Evidence of differences among study groups was found in HbA1c throughout the study (p<0.0001, Table 9), with Composition A (p<0.0001) and Composition B (p<0.0001) having lower HbA1c than the vehicle, and all the other drug combinations (p<0.001). The estimated overall level of HbA1c in the Composition A group (4.75) estimated to be 1.1% absolutely lower than Composition B (5.83, p<0.0001). The HbA1c level over the time-course of the study varied between treatments (FIG. 2, interaction: p<0.0001). The HbA1c in the Composition A group stayed approximately the same as at baseline. HbA1c increased in Composition B over time but not as much as the other treatments.

Insulin measurements were significantly different among treatments (p<0.0001, Table 10) with Composition A (p<0.0001) and Composition B (p=0.0054) having higher insulin levels at 20 days than the vehicle, and no evidence of a difference between the vehicle and 1K-MET (p=0.2955). The Composition A group achieved an estimated average of 10,186 (pg/mL) by day 20, which is significantly greater (p<0.0001) than Composition B (5259 pg/mL).

There was significant (p<0.0001) difference in average Creatinine levels between treatment groups. Creatinine levels in the Composition A (p<0.0001) and Composition B (p=0.0082) groups were lower than the vehicle group. The Composition A group had a significantly lower (p<0.001) level of creatinine (0.69 mg/dL) than the Composition B group (0.75 mg/dL). Creatinine levels were similar throughout the study in the Composition A and Composition B groups, with levels increasing in the other study groups (FIG. 3).

Both of the Composition A and Composition B groups showed lower WBC, HbA1c, reatinine, and higher insulin levels relative to the control group. The 1K-MET group, on the other hand, showed essentially no difference for all the measurements compared to the control.

ULD Compositions A and B reduced blood glucose and HbA1c suggesting a potential therapeutic effect at ultra-low doses. ULD Compositions A and B prevented or reduced the fall in insulin suggesting preserved pancreatic beta-cell function at ultra-low doses. Similarly, ULD Compositions A and B prevented or reduced the increase in creatinine suggesting preserved renal function at ultra-low doses. The effects of triple ULD combinations that included an SGLT-2 antagonist were greater than those of a ULD combination that did not include an SGLT-2 antagonist, suggesting drug-specific treatment benefits. The effects of triple ULD combinations that included an SGLT-2 antagonist were greater than those of standard-dose metformin. The effects of Composition A on all outcomes were greater than Composition B, indicating differences in the effects of ULD dapagliflozin compared with ULD empagliflozin
